YingTeng new air conditioning units are the result of years of professional production experience for our company, integrating the strengths of various domestic and international high-quality products to develop air conditioning units with advanced domestic levels to meet user needs. These units can achieve multiple functions such as heating, cooling, humidifying, and filtering/purifying the air. They are widely used in comfort cooling systems for large and medium-sized public buildings such as hotels, shopping malls, airports, hospitals, and office buildings, as well as in process cooling systems for industries such as electronics, textiles, chemicals, pharmaceuticals, and food.

The YingTeng explosion-proof fresh air air conditioning unit boasts superior cooling and heating performance, low noise, high compactness, light weight, and easy installation and maintenance. Moreover, equipped with a frequency or pressure variable speed controller, it can operate with variable air volume for energy-saving purposes, matching different seasonal conditions and on-site air conditioning scenarios. Therefore, it is particularly suitable for use in various air conditioning projects where space is limited.

Features of Explosion-proof Fresh Air Air Conditioning Unit

Enclosure

The cabinet is composed of low thermal resistance wall panels made by assembling high-sealing profile frames with color steel plates. The frame is made of aluminum alloy profile skeleton: the wall panels are made of integral polyurethane foam with a thermal conductivity of: λ=0.022 W/m·K. High-density polyethylene wall panels or glass wool wall panels can also be used. This structure is resistant to rust and corrosion, aesthetically pleasing, and durable with minimal air leakage rate.

Fan

Utilizing low-noise, high-efficiency external rotor centrifugal fans, the fans are precision dynamically balanced to ensure smooth operation of the unit, featuring low noise and high total pressure.

Cooling Plate

The condenser core is made of seamless copper tubes and high-purity aluminum foil, which are tightly integrated through advanced mechanical or hydraulic expansion technology. Afterward, it undergoes a 2.8MPa pressure seal leak test, meeting the American ARI standards. This ensures the product's superior performance and reliable quality.

Dry Condensate Pan

Precision-engineered condensate trays and extra-thick thermal insulation ensure that the unit operates without condensation or dripping in harsh environmental conditions. The condensate trays are slightly inclined for efficient drainage. Additionally, the condensate pipes are designed for non-full flow, providing a discharge capacity five times greater than the unit's normal operation discharge. Timely discharge of condensate reduces the "contact time" on the trays, benefiting both in reducing corrosion and preventing bacterial growth, thereby ensuring indoor air quality.

Air Filter

Specially designed modular filter plates can be easily removed from either side or top/bottom of the unit, making them particularly suitable for maintenance and cleaning in space-constrained environments. The filter media can be made of nylon corrugated mesh or non-woven fabric.
